CORKWOOD FACING FOR MANGLE ROLLS AND THE LIKE.

Application filed January 12, 1923. Serial No. 612,298.

- An Object of this invention is to provide a mangle for ironing and other laundermg and similar purposes with a facing capable of effecting the desired pressure and affording also sutficient yieldability to permit buttonsrand other fragile or rigid adjunct of clothing and the like to pass therethrough v without substantial injury. g

Heretofore, as generally practiced at the present time, it has been customary in mangling machines to apply felt. layers or other elastic material enclosed in windings of linen, duck or the like on the cylindrical face of a mangling roll; however, the steam released in the ironing operation is absorbed by the felt and fabric layers and the heat attendin the ironing operation, effect continued shrinkage and hardening of the felt. Such procedure has been improved upon by securing blocks or strips of corkwood to, the cylindrical surface of the iron or steel mangling roll.

However, natural cork wood in such good quality as .to give satisfactory results, is limited to blocks or strips of about 12 mches in length by 6 inches in width and considerable time is required in gluing or otherwise securing. the required number of these on the. cylinder and in cutting the contiguous edges of the cork strips to obtain close lit.

Pursuant to the present invention, the facing of the mangling iron is provided in the form of a complete ring of cork material fully completed at the place of manufacture and requiring but the mere slipping on of the ring overthe mangling iron. Such ring is preferably formed of an inner ring of composition cork compressed and molded to be substantially inexpansible and non-contractible under temperature variations and an outer ring of natural cork wood secured to the inner ring of composition cork, such outer ring being formed of blocks of natural cork wood, the inner faces of which are shaped correspondingly and secured to the outer face of the inner ring of composition cork, the outer face of the outer ring of natural cork wood beingeventually protected by a moisture and heat proof lacquer, varnish or the like. By the procedure of the present invention, the facing for the mangling irons may be formed of sections, which sections are slid on and keyed or Fig. 2 is a sectional elevation-on line 2- 2,

of Fig. 1; r I

Fig. 3 is a detail sectional elevation of the facing taken on line 3-3of Fig. 2; and.

Fig. 4 is a detail side elevation of Fig. 1, showing a section of the facing removedand another section partially moved out ofposition'. a V

Referring to the drawings, the I roll 10 represents a roll of a mangling machine or otliier form of laundering apparatus and the li e..

noted 12, 13, 14, 15, 16 as illustrated in Fig. 1, and such sections are longitudinally retained in position on the roll 10 by means ofthe end clamps 17,18.

Each section is preferably formed. of an inner ring 20, constructed of composition man lino iron and The facing 11, is formed of sections (16?,

cork, formed of molded and compressed granules or particles of cork wood bonded to one another to be inexpansible under increase of'temperature and moisture, as for example as is set forth in the United States Patent No. 484,345, granted to J. T. Smith, under date October 11, 1892. Preferably, the inner surface of the ring 20 is non-circular, such as the key surface 21 corresponding to and coacting with the key surface 22 formed on the surface of the mangle roll 10, see Fig. 4.

To the inner ring 20 of composition cork is applied the outer ring 23 of natural cork wood, as in the form of blocks, having their inner faces 24 conforming to the outer face of the ring 20 and secured thereto in any suitable manner, and the mutually engaging, lateral faces of the blocks 23, shaped to conform to one another and secured together. The outer faces of the blocks and according- 1y of the outer ring 23 are shaped to the desired cylindrical form.

' Preferably, a coating of waterproof material is applied to the outer face of the ring 23 to safeguard against the entry of absorption of moisture from the articles laundered in the mangling machine. Sheeting of cotton or linen may be applied over the natural corkwood ring, as will be understood. H

By means of the above arrangement, the required number of sections of my improved facing are slipped on the mangling roll 10 and set in position by means of the end clamps 17 18, to prevent displacement of the sections longitudinally of the roll 10. Circumferential displacement of the sections is prevented by the keying effected by the conjoint faces 21, 22.

If it is desired to replace any section. an end clamp, such as the left-hand end clamp 18, is removed from the mangling roll 10, see Fig. 4, and the section desired to be removed, say the section 15, is slid longitudinally to the left of the roll 10, after removing the end section 1 6, see Fig. 4.

The blocks 23 of natural cork wood are preferably keyed to the inner ring 20 of composition cork by means of the elevations 27 in the outer face of the inner ring 20 and corresponding depressions 28 on the inner faces 24; of the blocks 23.

The above described invention provides for the desired rigidity coupled with yieldability for ironing garments or the like of linen, cotton, and like fabrics while at the same time permitting buttons and like addenda to pass without substantial injury between the mangling roll and the heated bed of steel or the like.

In the presence of heat and moisture, incident to the ironing operation, the inner ringmaint-ains its diameter and the adhesive between the inner ring and the outer surface of the outer ring is protected from moisture. The outer cylindrical surface of the outer ring lends itself readily to the linen or cotton covering and enhances the ironing operation.

Pursuant to the above, the facing or sections of facing for the mangling rod are advantageously completed in the place of manufacture and are fully prepared for ready mountingron the iii-angling roll, even by unskilled help. The invention is also advantageous in affording the ready substitution of any particular section without loss of the facing as a whole.

For certain uses, the inner core of composition cork may be substituted by molded paper pulp, or molded asbestos composition, or by certain metals and the like, to which inner core, the outer core of natural cork wood is applied as hereinabove set forth.

\Vhereas l have described my invention by reference to specific forms thereof it will be understood that many changes and modifications may be made without departing from the spirit of the invention.

I claim:

1. A new article of manufacture comprising a unit for a facing of mangling rolls and the like, formed of an outer ring of bloc'ks'of natural corkwood permanently secured to one another and to an inner ring of molded, moisture and heat resisting composition cork.

'2. A new article of manufacture comprising a unit for a facing of a mangle roll or the like, formed of an outer ring of blocks of natural corkwood pcrimiueutly secured to one another and to an inner integral ring of molded, moisture and heat resisting cork material.

In testimony whereof I have signed this specification this 9th day of January, 1923.

ENRIQUE VINCKE.
